"Wife Swap" star Alicia Guastaferro will no longer be facing prostitution charges for an incident at a New York Thruway rest stop this summer.

The 21-year-old Williamsville, N.Y. resident was arrested in August at a service area in Pembroke, 30 miles outside of Buffalo, with a Rochester lawyer who was "slumped over asleep" at the wheel of a parked car. James D. Doyle, who previously served on the Greece Town Board, was accused of paying the former reality star for sex among other charges.

At the time police said Guastaferro, then 20 years old, was half-naked in the car and drunk. She reportedly told investigators she was paid to perform sex acts and spend the night with Doyle multiple times, and that he gave her a fake ID and bought her alcohol.

However, TMZ reports the District Attorney's Office dropped her prostitution charges at her court appearance on Tuesday in the "interest of justice." She still faces charges of criminal impersonation and possession of a controlled substance.

Last month, YNN reported charges of patronizing a prostitute were dismissed against Doyle, but the 54-year-old attorney still faces charges for DWI, traffic and providing alcohol to a minor. Guastaferro didn't turn 21 until later this year.

Doyle, who has always denied the charges, is due back in court February 12th. Guastaferro will appear before a judge again on March 12.

Guastaferro has appeared in court several times before, The Associated Press notes. She's currently a plaintiff in a pending lawsuit claiming she and other exotic dancers were denied overtime pay at a strip club where she worked.

The former teen beauty queen also sued ABC and its parent company Walt Disney for $100 million in 2010, claiming they poorly represented her on "Wife Swap" in 2008 as a "spoiled brat." The lawsuit was settled last year at undisclosed terms.

Her parents were sentenced in federal court after pleading guilty to criminal charges last year, the AP adds. Ralph Guastaferro was sentenced to two years in prison last year for laundering $1.2 million in a Canadian telemarketing scheme and his wife Karen received three years probation for paying employees of the couple's glass-tinting business off the books.
